条件表达式中的 zipmap 函数给出真假结果表达式必须具有一致的类型错误

Question

变量： ingress_ports_udp 是带有逗号分隔值的字符串类型。 ingress_cidr_udp 是带有逗号分隔值的字符串类型。

代码：

  dynamic "ingress" {
    iterator           = rule
    for_each           = zipmap(split(",", var.ingress_ports_udp),split(",", var.ingress_cidr_udp)) != "" ? zipmap(split(",", var.ingress_ports_udp),split(",", var.ingress_cidr_udp)) : ""
    content {
      from_port        = rule.key
      to_port          = rule.key
      protocol         = "udp"
      cidr_blocks      = rule.value
    }
  }

问题： 表达式 zipmap(split(",", var.ingress_ports_udp),split(",", var.ingress_cidr_udp)) != "" 出现错误？ zipmap(split(",", var.ingress_ports_udp),split(",", var.ingress_cidr_udp)) : ""

要求： 如果 zipmap(split(",", var.ingress_ports_udp),split(",", var.ingress_cidr_udp)) 为空，即 ingress_ports_udp 和 ingress_cidr_udp 字符串类型为空，我不想运行动态入口块。 请帮忙。

Answer 1

false 不能使用空字符串，因为它的类型与true 条件的结果不同。您可以检查：

for_each           = zipmap(split(",", var.ingress_ports_udp),split(",", var.ingress_cidr_udp)) != "" ? zipmap(split(",", var.ingress_ports_udp),split(",", var.ingress_cidr_udp)) : {}
